Target Output, Extended Output and Site Productivity: Tales of the Expected

Target output, extended output and moderate output  are compared for selected construction projects  in some selected sites in Nigeria. The objective of this study is to examine the attributes of extended and moderate output, setting of benchmarks for purpose of  analysis of worker productivity, determination of derivable benefits, with a view to identifying if the effect are the same for both methods. The study procures the primary data used in this study through the use of questionnaires designed in Likert scale 1 to 5, which are sent to clients, builders and consultants. In all, 120 questionnaires were sent to these respondents who recently completed their housing projects based on the two methods. Results of the study indicate that there is  significant difference between both methods in terms of risks of value for money, guaranteed sense of self accomplishment, while a significant difference exists between both methods in job burnt- out effect, timely completion of project, and exhaustion, Moderate target output method demonstrates less risk of timely completion of project than the extended target output.  This study concludes that there are various types of risks inherent in use of both methods in housing projects. The study displays characteristics of early completion of project and prospects of getting good value for money. Recommendations of the study are that clients, contractors and consultants should use Moderate target output for execution of their future housing projects job allocations, and also they are at liberty to use any of the two methods as they best satisfy their requirements. Implications of this study to policy makers and other stakeholders in the construction industry is that  Moderate labour output method should be explored for use in large and complex projects as  considerable cost savings can be achieved, timely delivery of project and good value for money are equally derivable benefits of the method.  The outcome of this study serves as a watershed to other peculiar issues inn site productivity and job beats’ allocations.

Survey dataset on occupational hazards on construction sites

The construction site provides an unfriendly working conditions, exposing workers to one of the harshest environments at a workplace. In this dataset, a structured questionnaire was design directed to thirty-five (35) craftsmen selected through a purposive sampling technique on various construction sites in one of the most populous cities in sub-Saharan Africa. The set of descriptive statistics is presented with tables, stacked bar chats and pie charts. Common occupational health conditions affecting the cardiovascular, respiratory and musculoskeletal systems of craftsmen on construction sites were identified. The effects of occupational health hazards on craftsmen and on construction project performance can be determined when the data is analyzed. Moreover, contractors’ commitment to occupational health and safety (OHS) can be obtained from the analysis of the survey data.

Survey dataset on work-life conflict of women in the construction industry

Work-life conflict can have a detrimental effect on family life, particularly for women who have to work in order to support their families financially. The data set presents the views of 50 female construction professionals in Lagos, Nigeria through a purposive sampling technique with the aid of questionnaire. Categorical Regression was used to assess the effect of work pressure on family expectations. The features of the respondents in terms of profession, years of experience, office location and household characteristics were presented in bar chart. Analysis of the data can provide information on the work experiences of women in the construction industry particularly work load, hours worked per day, work on weekends and work on holidays. The data can also provide insights on the family expectations that are significantly affected by work pressure

Dataset for material logistics on construction sites

Data exploration of social client relationship management (CRM 2.0) adoption in the Nigerian construction business

Integrating social client relationship management (CRM 2.0) in the built environment can enhance the relationship between construction organizations and client towards sustaining a long and lasting collaboration. The data exploration analyzed the e-readiness of contracting and consulting construction firms in the uptake of CRM 2.0 and the barriers encountered in the adoption of the modern business tool. The targeted organizations consist of seventy five (75) construction businesses operating in Lagos State which were selected from a pool of registered contracting and consulting construction firms using random sampling technique. Descriptive statistics of the e-readiness of contracting and consulting construction firms for CRM 2.0 adoption and barriers limiting its uptake were analyzed. Also, inferential analysis using Mann–Whitney U statistical and independent sample t-test was performed on the dataset obtained. The data generated will support construction firms on the necessity to engage in client social relationship management in ensuring sustainable client relationship management in the built environment.

Survey datasets on women participation in green jobs in the construction industry

The unique qualities of women can make them bearers of solutions towards achieving sustainability and dealing with the dangers attributed to climate change. The attitudinal study utilized a questionnaire instrument to obtain perception of female construction professionals. By using a well-structured questionnaire, data was obtained on women participating in green jobs in the construction Industry. Descriptive statistics is performed on the collected data and presented in tables and mean scores (MS). In addition, inferential statistics of categorical regression was performed on the data to determine the level of influence (beta factor) the identified barriers had on the level of participation in green jobs. Barriers and the socio-economic benefits which can guide policies and actions on attracting, retaining and exploring the capabilities of women in green jobs can be obtained from the survey data when analyzed

Survey datasets on categories of factors militating against safety practices on construction sites

The causes of occupational accidents have been classified into unsafe conditions and unsafe behaviour. Interestingly, numerous authors have contributed to the issues of safety practices in managing building production process with different views on factors causing construction accident and insensitiveness to safety practices, but there have been a little efforts to bring together major causes and factors militating against safety practices in unified manners. Therefore, all identified forty nine factors from literature review [1–32] were brought together and grouped into five different categories. Descriptive statistics were performed on the data to rank these factors as affected workmen on construction sites. The results were presented in figures, text file and tables using Mean Score. The data presented in this study were enable construction managers to standardize project risks assessment and management.
